Title: Foot pedal control mechanism for l hydrostatic transmission vehicles
IPC: B60W10/10
Filed: 1975-10-15
Abstract: 1473059 Hydrostatic transmission control; linkwork TOWMOTOR CORP 15 Oct 1975 [30 Jan 1975] 42220/75 Headings F2W and F2K The variable displacement pump 14 of a hydrostatic transmission and the control lever 22 of a prime mover 16 are conjointly controlled by a single control member 26 which is pivoted in either direction from a neutral position to adjust the pump 14 for forward or reverse drive, by pivoting a pump control member 24, and to adjust the control lever 22 to increase prime mover power, the control lever 22 being moved in the same direction whether the pump is adjusted for forward or reverse and the linkage connecting the pump control member 24 and the control member 26 including a resilient link 42 so that the prime mover power can be further increased after the pump has been adjusted to maximum displacement. The control member 26 comprises a pedal, pivoted to adjust pump control member 24 through link 31, bell crank 34 and resilient link 42 (Fig. 2, not shown). Pivoting of pedal 26 also rotates a rod 37 which has a link 61 at one end to which two links 62 and 63 are pivoted. Links 62 and 63 are pivoted to links 68 and 69 respectively, rotatably mounted on a rod 71 which has a pin 79 passed through it, engaged by a pin 81 of link 68 for one direction of pivoting of pedal 26 and engaged by a pin 82 of link 69 for the other direction of pivoting of pedal 26. Thus the rod 71 pivots in the same sense for forward or reverse pivoting of pedal 26 and, through links 74 and 76, pivots the prime mover control 22 in the same direction. Prime mover 16 can be such as to be controlled by a throttle lever, governor rack or rheostat. The pump 14 is controlled through a valve assembly 23. An inching pedal 83 is provided, it moving a valve spool 84 of the valve assembly 23. The linkage may be spring biased to return the transmission to neutral on release of pedal 26. The vehicle shown is an industrial lift truck, hydraulic motors 19 driving wheels 21.

Filed: 1966-09-21
Abstract: 1,113,744. Continuous casting. CONCAST Inc. 21 Sept., 1966 [22 Sept., 1965], No. 42247/66. Heading B3F. A longitudinally-reciprocated arcuate mould 1 is guided in its approximate part-circular path by at least one short pivoted lever 12 or 17 disposed so that when the mould is in its central position as shown, the point 23, on a line 22 joining the centre 8 of the arcuate axis 7 of the mould cavity 2 and the mouldcavity centre 11, nearest to the longitudinal axis 21 or 25 of the lever 12 or 17, produced, is spaced from the mould-cavity centre 11 by a distance at least half the distance between the centres 11, 8. As shown, the produced lever axes 21, 25 intersect at a point which is at their minimum distance 24 from the line 22. The lever axes produced, 21<SP>1</SP> and 25<SP>1</SP>, may intersect on the axis 10 of the imaginary cylinder 9 on which lies the arcuate axis 7 of the mould or may intersect below the level of the line 22. The levers are pivoted at one end to the mould 1 and at the other to a rigid support 15 on the plant structure. There may be one short lever, Figs. 2-4 (not shown), pivoted nearer one end of the mould while the other end is guided by a mould pin (40 or 50), guided in a slideway, or by a roller (64) moving on a guide (60). The mould is reciprocated by a disc cam or eccentric (69). The levers may be provided on both sides of the mould or they may be bifurcated for the same effect.

Title: Hydraulic control device
IPC: F15B13/08
Filed: 1973-09-07
Abstract: 1397914 Hydraulic control circuits ROBERT BOSCH GmbH 7 Sept 1973 [11 Sept 1972 13 Jan 1973] 42272/73 Heading F1P [Also in Division F2]  In a control circuit, Fig. 1, in which seat-valves 16, 17, designed for controlling single-acting loads control supply and return to rams 13, 12 and also influence a control line 33 which controls a changeover valve 32 for by-passing pressure fluid from a pump 35 to a reservoir 37, a pressure control valve 51 is provided between the changeover valve 32 and the reservoir 37 and a conduit 45 leads from the connection between valves 31 and 32. As described the rams control the raising and tilting of a loading side wall of a vehicle. Assuming the side wall to be raised and pivoted inwards the system operates as follows. Valve 17 is moved to position 25 to pivot the side wall outwards, this does not operate a limit switch 28 so the pump 35 is inoperative. Pressure relief valve is latched open by ratchet 53 so the side wall can pivot outwards under its own weight. Fluid thus flows from chamber 40 of ram 12 to reservoir 37 and is drawn from reservoir 37 through duct 45 into chamber 46. If the side wall does not pivot under its own weight because the vehicle is tilted an actuator 52 unlatches valve 51  and at the same time a cam 54 operates a switch 55. This switches on the pump 35 and fluid flows through ducts 34, 19, 31, valves 32, 51 to reservoir 37. According to the setting of pressure relief valve 44 pressure in duct 43 is restricted and this pressure is available via duct 45 in chamber 46 to urge the side wall down. Valve 17 is moved to position 24 to tilt the side wall inwards. This operates switch 28 and pump 35 which feeds fluid through duct 19, valve 17 and duct 39 to the chamber 40. Valve 16 in position 24 causes ram 13 to lift the side wall and in position 25 to lower it. Pump 35 is operative only for lifting in which event changeover valve 32 is closed. Figs. 2-4 and 6-8, (not shown), illustrate modified circuits which operate in a similar manner. Fig. 5 shows a construction of seat valve in which ports 19, 21 are controlled by valves 91, 92. Spool portions 93, 94 of the latter open and close control duct ports 33, 83. Rotation of a handle 95 causes sliding of the valve members by pressure applied to spool portions 93, 94.

Filed: 1972-09-12
Abstract: 1382719 Mixing controlled by viscosity PARKE DAVIS & CO 12 Sept 1972 [13 March 1972] 42388/72 Heading B1C Every time a capsule former is dipped into a dish 10 of gelatin solution and withdrawn, an incremental addition of relatively more viscous solution is added from a supply 12. The viscosity of the solution in dish 10 is continuously sampled by a viscosimeter 16 generating a pneumatic analog signal (in the form of the back-pressure in line 23) which is amplified in a pressure transmitter 30 and supplied to a means 50 where it is balanced against a reference signal derived from the constant pressure supply 20 and controller 40; if the viscosimeter signal is greater than the reference signal the means 50 transmits a pneumatic signal through line 52 to a valve 60 which thereupon opens briefly and closes again. Cleansing a small quantity of water to be delivered to dish 10 through line 15. Several such quantities of water may be necessary to restore the desired viscosity and generally the next signal has reached valve 60 before the water delivered has had time to affect the analog signal representing the viscosity. The quantity delivered each time is controlled by the setting of valve 80.

Abstract: 1,155,912. Liquid filter. BENDIX CORP. 23 Sept., 1966 [30 Sept., 1965], No. 42661/66. Heading B1D. A filter element for liquid fuels comprises an edge-type assembly of paper washers or helically wound ribbon 30 in a protecting case 26 and compressed by a piston 36 subject to the differential pressure across assembly 30, piston 36 carrying a valve member 42 adapted to close the outlet 40 when accumulating water or solids raises the differential pressure sufficiently. To prevent the valve opening again on reduction of differential pressure, e.g. resuiting from its closure, the piston 36 and Valve member 42 are connected by a soft wire having a deformable S shaped part 46, which straightens out when piston 36 returns to leave the valve closed (Fig. 4, not shown). The valve member 42 and seat 40 include an angle of 15 degrees, so that the valve tends to jam in the closed position. A plurality of such elements are located in a common housing (Fig. 1, not shown).

Abstract: 986,651. Woodworking. WADKIN Ltd. March 12, 1964 [Dec. 12, 1962], No. 42676/62 Heading B5L. A woodworking machine such as a planing or moulding machine, comprises a pressure feed arrangement having a work-engaging feed roller 14 urged against a workpiece by a fluid pressure operated cylinder 19, the force of which is maintained approximately constant throughout its stroke by a pressure control device. As described, the machine has two feed rollers which are mounted on arms 15 movable about a common pivot 16, the arms having extensions 17 connected by links 18 to fluid pressure operated cylinders 19. The rollers are driven from a gear mounted coaxial with the pivot 16 and co-operate with freely-rotatable rollers 12 which extend through openings 13 in a table 11 of the machine. In an alternative embodiment, the feed rollers are mounted on arms mounted on separate pivots outwardly of the rollers, the cylinders being mounted on a casing 25. The pressure control device may comprise a blowoff valve in the circuit to the pressure side of the cylinders, the circuit also having a reversing valve. whereby the supply to the cylinders is reversed to raise the feed rollers. A verticallyadjustable bracket 29 is secured to the casing 25 at the infeed end of the machine and has a pivotally mounted feeler 34 which is moved in the event of an oversize workpiece being fed to the machine and operates a valve in the upper part 30 of the bracket to cause actuation of the reversing valve so that the feed rollers 14 are raised to render the machine inoperative. If a low workpiece is followed by a fairly high workpiece which, although it does not actuate the feeler 34, is not acceptable by the feed rollers 14 because of their low position, a second feeler device is operated, the device having an adjustable casing 41 supporting side pressure rollers 44 and a feeler arm 51 which normally bears against the side faces of the workpiece. When a fairly high workpiece following a low workpiece is held back by the feed rollers, the feeler arm detects the gap between the workpiece and rocks about a pivot 49 to move a lever arm 48 connected to a valve 45 which actuates the reversing valve to lift the feed rollers.
